Pollucite and Tremolite Chemical Formula
While comparing Pollucite and Tremolite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Pollucite and Tremolite chemical formula.

Pollucite and Tremolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pollucite and Tremolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pollucite and Tremolite Optical Properties during the identification of gemstone. Specific gravity of Pollucite is 2.95-3.07 whereas that of Tremolite is 2.95-3.07.
